A RESEARCH PAPER ON - “STUDY ON COST ANALYSIS OF R.C.C AND COMPOSITE STRUCTURE”

Abstract

Structural engineers are facing the challenge of striving for most efficient and economical design solutions while ensuring final design of a building to be serviceable for its intended function, habitable for its occupants and safe over its design life-time. As our country is the fastest growing country across the globe and need of shelter with higher land cost in major cities where further horizontal expansion is not much possible due to space shortage, we are left with the solution of vertical expansion.
Steel-concrete composite construction has gained wide acceptance worldwide as an alternative to pure steel and pure concrete construction. Reinforced concrete members are used in the framing system for most of the buildings since this is the most convenient and economic system for low-rise buildings. However, for medium to high-rise buildings this type of structure is no longer economical because of increased dead load, less stiffness, span restriction and hazardous formwork. Steel-concrete composite frame system can provide an effective and economic solution to most of these problems in medium to high rise buildings. An attempt has been made in this study to explore cost effectiveness of composite construction. Steel-concrete composite construction with castellated steel beams for large span member is economical in construction, which also saves lot of time and money in construction, which will help the planners to meet the demand with minimum time. This technology provides more carpet area than any other type of construction Composite construction also enhances life expectancy of structures. Hence, the aim of present study is to ultimately compare cost of R.C.C. structures, Composite structure with solid sections and composite structure with openings. All frames are designed under same gravity loading. Equivalent static method of analysis is used for Seismic force analysis. Etabs software is used and the results are compared Cost effectiveness based on material cost for all types of buildings models is determined.
